Thanks to everyone for all the responses. They are very helpful.
SJG: I agree with everything you posted, as it is consistent with my research in NJ and Fed. statutes, and NJ State Police website, etc.
I am fortunate that I was recently able to retire and make FL my state of domicile. I can't take all the NJ regulations, taxes, etc. anymore. I'm fine with just spending my summers at the Jersey shore and the rest of my time in FL. I'll love NJ, but enough is enough.
By the way, I found this NJ statute that suggests you need to file for a new FID when there is a change of residence, if you want to continue to use your FID. There may be some FFLs that don't care if the FID and drivers license addresses don't match, but the law seems to require it. I think I'm just going to apply for a new FID with my FL address.
